invoke java method error.

[ysong2123]

here is my issue:
in java: i have defined a Class Calculator which contains method -- public Value run(Value... inputs). And a little test data has been prepared for testing this method --

    Value[] inputs = new Value[2];
    inputs[0] = Value.create(0.6);
    inputs[1] = Value.create(0.7);

and then run calculator.run(inputs).

Now, for business purpose, i have to implement this unit test using python again and the corresponding java class: Value and Calculator will be reused by leveraging jnius. Here is my python code:
solution 1:

    ArrayList = autoclass('java.util.ArrayList')
    list = ArrayList()
    list.add(Value.create(0.6))
    list.add(Value.create(0.7))
    calculator.run(list.toArray())

and then the exception has been thrown:
jnius.JavaException: JVM exception occurred: java.lang.ArrayStoreException.

solution 2:

import numpy as np
inputs = [Value.create(0.6), Value.create(0.7)]
calculator.run(np.array(inputs))
and then thrown:
jnius.JavaException: Invalid variable (array([<com/***/Value at 0x7f8a985599e8 jclass=com/***/Value jself=<LocalRef obj=0x7f8ac3d751f8 at 0x7f8a9852c4b0>>,
       <com.***.Value at 0x7f8a98559990 jclass=com/***/Value jself=<LocalRef obj=0x7f8ac3d751f0 at 0x7f8a9852c930>>],
      dtype=object),) used for L array 'Lcom/***/Value;'

Do you know how to implement the same semantics as shown in java?

Value[] inputs = new Value[2];
    inputs[0] = Value.create(0.6);
    inputs[1] = Value.create(0.7);

and then run calculator.run(inputs).

Thanks very much!
